Issues today with CDG-YYZ flight being delayed out of Paris which meant we were going to missconnect in YYZ. Upon deplaning we were greeted by a fantastic concierge, Anna, who did everything possible so we could catch our original flight but it was too tight (way too tight). We were already protected on the next flight and Vicky, a very efficient agent at the customer desk took care of the rest. Great team work! TY.
